An Army outgunned, early article pushing the Grendel

[LRRPF52]

Looking at the new weapon design it would be nice if they built one short enough for the 6ARC/6.5 Grendel rounds, Not saying you need 80K psi but 65 K psi would add a bit of punch. While doing so maybe lengthen it to be able to handle a 2.5 length cartridge overall length. Maybe a Grendel case with the shoulder moved forward just a bit with a bit more taper, possibly 23 degrees to aid functioning. That would make matching the 7.62x51 easy. I actually like the AR15 design myself but if they were to build one just a bit longer and with a larger diameter bolt designed for a .441 case head I think it would be a better overall package. That and 65K psi would make a lot of difference.

That was called the .264 USA:
